Opinions on best option: truck manifolds are too big on 5.3 LS

Hello,

I'm installing a 5.3 LS from a '03 Silverado in my 1937 Chevrolet 4 door. As you can see in the picture the exhaust manifolds aren't going to fit. I'm wondering what is the most reasonable option. This is going to be a daily driver for my wife and we're not looking to win any races, just carry our family around. I have read that these years motors had very good manifolds and that shorty headers wouldn't be any better than stock manifolds, but I'm not sure if stock manifolds would clear in this situation. I usually work on old stock motors and I'm not sure about the reliability of new headers. We intend to drive this car for the rest of our lives and are looking for the most reliable option. I'm not sure about all the available stock options.



Thank you,
Brandon
